For opening the doors. of garages," fire houses, and thelike, wherein vehicles are stored, the vehiclesare provided with .door

opening controls. (See Figures 9,-10',1l; ,7 The'underside of the floor boards of the vehicle is provided with; the brackets 545-54 whic ppo he casings ..i wh h n turn, providebearings for} the transverse" shaft 56. The -push-.- pedal 57 projectsup wardthroughthefioor,board 58 withincon- V ven-ient reach. offthe heel of the driver of Therewind. spring GO 'has one end r to the shaft 56 and the other; fixed-tothe V adj acent casingl'55, to rewind the shaft after the thrust of e pedal '57.

he-irack teeth 60, enmeshed with the pinion 61-, fixed on the-shaft56,

Suitable drumsare fixed to the' sh-laft'56 within the casings 5555 to which one of the ends of thechains 62, 63 are fixed, so that. i

the chains wind or unwind'as:the'shaft' 56 is rotated.

Pushing the remotej control pedal down unwinds these chains, which descendthrough theCaSingS-at 6 n i t y r p n e tact platesfas at A-"-B. This closes'the ac tuating circuit through the; chain '62 back to the chain 63 ,whichis grounded in the auto- 7 mobile battery control; circuit (see Figure 15,) until the pedal is releasedand the spring '60 rewinds the ch ins and opens the circuit.

Closing the.circuitasdescribed causes curg by shortening the plates AB, since there is rename rent to'fiow from the battery 65, across the switch 66, to the chain 62, to the plate A (see Figure 15.) From A it flows over the line 66 through the magnet 67, thence over theline 68. to the plate B and over the grounded line 69 back to the battery 65.

Energizing the magnet 67 (see Figures 12,

13, 14:) attracts the armature 70 mounted on the dielectric bar 71, which closes the three pole contacts on the open side of the magnetic switch G. This permits the current to flow from the generator 72, over 73 to 741,;

through the magnetic field 75, 76 of the motors 18, 19 in the opening direction, thence over 77 across the G'switch contacts 78, 79 to 80, thence back to the generator. From the generator 72 over 73, the current also passes from contacts 81, 82 of G to 83,

through the armatures 84, 85 of the motors 18, 19, to 86, across contacts 87, 88, 78, 79 to 80 and thence back to the generator 72. i

, The magnetic latch 49 is in a shunt circuit 89, 90, 91 with the opening magnet 67, to release the latch 49 simultaneously with the closing of the G switch. 7

Thus utilizing the automobile battery 65 makes it impossible to open the doors 1, 2

no other source of power in the AB circuit.

The motors 18, 19 will continue to tunetion in the generator motor circuit until the doors 1, 2 are fully open and the trips 50, 51 have tripped their respective clutches out of engagement, as described.

The plates 0-D are located within the garage. .The automobile is driven into the garage as soon as the doors arefully open.

across G to 88, 78, 97, 80 and back to the generator 72. v

The motors are thus reversed by reversing the directionof the current flow through their armatures. The motors continue to operate to fully close the doors, until declutched by the trips 52, 53

The motors 18, 19 may be separately wired to the magnetic switch. In this case, the switch contacts may be timed so that the motor 19 receives current slightly ahead of the motor 18 to insure the proper functioning of the latch mechanism.

When the doors are fully closed the pedal 57 is released and the chains 62, 63 raised from contact with the plates CD by the rewind spring 60', as described.

If it is desired to. operate" the doors: l-Ild$- pendent of the automobile, they] can. be;

opened by closingthe switch 98. The cur rent. then flows from. the.v battery 99;- across switch 98 to 89, through the latch 49,, and

magnet, 67, thence over and 91 backtothe battery. .Energizing the open magnet 67 Closes themotor circuit toyopen the doors; as

previously described.

The operation isreversed by closing. the. switchlOO. The current then flows. from.

the battery 99 across. the switch 10.0; to: 92,;

through the close magnet 93 to 101,.backto the battery 99; Operating the, mag-net 9.3.

reverses the current through the motorgcircuitto close the doorsas described- The key switch 103 is mounted on the out-, side of the. doors and.v is connected: in parallel: with the opening switch 98. The doors may thus be; conveniently opened from the outside by closing; the key switch. Current, their flows fromjthe battery 99 across theswitch 103 to: 89 and, energizes the. open magnet.

to open the doors. 1

This key switch could, also beintroducedinto thejmotor circuit instead, if preferred. A transformer could be substituted for the; battery 99, and its circuits thus operated; elf: the motor circuit or other source ofjavailable current. 77 M I When the car is-backed out; ot the garage,

olt theplates C-D, the. pedal57i is depressed so that the chains 62,-63- will contact the plates EF, outside the garage doors.

The currentfiows' from the battery 65', over; switch 66 to plate; E, thence over 104,101, magnet 93, to plate F, thence over chain 63,

and ground to the battery 65, thus closing V the switch G to actuate the motor. circuit to close the doors 1, 2, from the automobile.

There are three distinct electric circuits.

The remote control circuit energized by the,

automobile battery 65; the

actuate or close the motor circuit selective-1y through the magnetic switch G; and the motor circuit energized by thegenerator72. The remote; control and actuating circuits are one in effect. i r o Having thus; described thisinvention what is claimed and desired to. scc ure'by- Letters. Patentisz' f 1.
